Can you try recreating an instance? May be you missed something & selected a wrong instance somehow.

@shadyabhi That of course will be final resort.

Can you replicate with another instance? A micro should fall in the free tier, or if you want a larger instance it's going to be a trivial cost for spin-up, check, spin-down.

This is definitely Amazon Linux (CentOS based), not Ubuntu. Another hint is that the default username in Amazon Linux is usually "ec2-user" while in Ubuntu it is "ubuntu" (at least if you use the default stock AMI). I don't know how it can be different from what you selected when you created it, but I guess it's either a human error or a weird bug.

Edit: For the record, the problem was that he was using an old EBS volume (which had Amazon AMI) as root volume.
